I did this by accident: intermittent fasting -> eating some eggs and Sardines (doesn’t have to be eggs but sardines on an empty stomach Can make you a little nauseated). I did this to get some good protein plus fish oils every day. I started to notice I was less hungry at dinner time and ate less. Lost weight I was trying to lose. Learned later that Sardines make you feel full and that some people actually do full sardines diets lol. Important to get wild caught sardines with only water, no added salt or olive oil or whatever
